See the basic definition of a diagnostic error. This will help you to clarify the main causes of the fault code. You will understand the program of the control unit
Basic DTC analysis according to OBD2 protocol standard.

OBD2 or On-Board Diagnostics displays messages for basic group styles. More comprehensible code composition has been standard since 2000. The DTC code consists of five characters and its composition will be shown in this video

Insight into programming

The basic unit for the operation of any computer is the bit. Logic 0 and 1 are expressed by a single bit. Diagnostics The error code is composed of 16 bits. The first two bits define one of the four basic circuits. The video will show you a comprehensive overview of the composition of the error report

HO2S Delayed Response Rich to Lean Bank 2 Sensor 2

Cause of DTC

Before the ECM can reports that DTC P013A, P013C, P013E, or P014A failed, DTCs P0030, P0031, P0032, P0050, P0051, P0052, P0135, and P0155 must run and pass. DTC P0036, P0037, P0038, P056, P0057, P0058, P0137, P0138, P0140, P0141, P0157, P0158, P0160, P0161, P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0442, P0443, P0455, P0458, P0459, P2096, P2097, P2098, P2099, P2177, P2178, P2179, P2088, P2089, P2090, P2232, P2235, P2270, P2271, P2272, or P2273 is not set. The ignition voltage is greater than 10 volts. The HO2S 1 and 2 are in closed loop. The HO2S 2 resistance is less than 900 ohms. The HO2S 2 has switched from lean to rich during the ignition cycle. The calculated exhaust gas mass flow rate is greater than 2.22 g s. The calculated exhaust gas temperature for HO2S 2 is warmer than 450°C (842°F). The HO2S 1 signal voltage is less than 141 mV The HO2S 2 signal voltage is greater than 590 mV at the beginning of decel fuel cut-off - DTC P013E and P014A only. The DTCs run continuously once the conditions above exist for greater than 4 seconds.
